Abstract
The invention belongs to the technical field of phase-change heat transfer enhancement, and particularly discloses a multifunctional surface structure and a preparation method and use thereof for condensation enhancement. The multifunctional surface structure for condensation enhancement includes a copper substrate. A plurality of Tesla valve passages are parallelly arranged on a surface of the copper substrate. A diamond bump with a flared slope is arranged on the surface of the copper substrate between each side passage and the corresponding main passage. The surface of the copper substrate and surfaces of the diamond bumps and the Tesla valve passages are covered with a composite hydrophobic coating. The heat-transfer performance of the surface structure is remarkably improved.
